Ballsy spammers

If you have to force a site to delete your own spam, you're doing it wrong.

Comment spam is the bane of one's life on the internet; there's probably some underneath this very post (if there isn't, there will be). Spammers post little messages with little relation to the content above, and link to their, generally scammy, site.

The intention isn't really to trick individuals to click on the post, because even spammers know that people don't tend to be that intrigued. Instead, it's to game Google Search rankings, which are determined by the number of sites which link back to yours.

For quite some time now, Google has deliberately ignored links in comments, knowing that they have nothing to do with the owner of the site. That hasn't stopped the spammers, of course, who aren't known for making sense, but it has at least dampened their effects. But recently, it went one step further, and started actively penalising sites which engage in spam.

All of which led to the American politics site, TPM, receiving a cease-and-desist letter from a spammer, asking them to delete previous spam from their site. Josh Marshall, the editor, writes:

In other words, the estimable businessmen and women at realinsurance.com.au have been paying SEO companies to spam the comment sections of sites around the globe. But now Google’s new search algorithms are making that legacy spam really damaging. So now they’re sending out cease and desist notices to the victims of their earlier spamming demanding that they search their archives and remove their spam.

Marcus Hutchins: What we know so far about the arrest of the hero hacker

The 23-year old who stopped the WannaCry malware which attacked the NHS has been arrested in the US. 

In May, Marcus Hutchins - who goes by the online name Malware Tech - became a national hero after "accidentally" discovering a way to stop the WannaCry virus that had paralysed parts of the NHS.

Now, the 23-year-old darling of cyber security is facing charges of cyber crime following a bizarre turn of events that have left many baffled. So what do we know about his indictment?

Arrest

Hutchins, from Ilfracombe in Devon, was reportedly arrested by the FBI in Las Vegas on Wednesday before travelling back from cyber security conferences Black Hat and Def Con.

He is now due to appear in court in Las Vegas later today after being accused of involvement with a piece of malware used to access people's bank accounts.

"Marcus Hutchins... a citizen and resident of the United Kingdom, was arrested in the United States on 2 August, 2017, in Las Vegas, Nevada, after a grand jury in the Eastern District of Wisconsin returned a six-count indictment against Hutchins for his role in creating and distributing the Kronos banking Trojan," said the US Department of Justice.

"The charges against Hutchins, and for which he was arrested, relate to alleged conduct that occurred between in or around July 2014 and July 2015."

His court appearance comes after he was arraigned in Las Vegas yesterday. He made no statement beyond a series of one-word answers to basic questions from the judge, the Guardian reports. A public defender said Hutchins had no criminal history and had previously cooperated with federal authorities. 

The malware

Kronos, a so-called Trojan, is a kind of malware that disguises itself as legitimate software while harvesting unsuspecting victims' online banking login details and other financial data.

It emerged in July 2014 on a Russian underground forum, where it was advertised for $7,000 (£5,330), a relatively high figure at the time, according to the BBC.

Shortly after it made the news, a video demonstrating the malware was posted to YouTube allegedly by Hutchins' co-defendant, who has not been named. Hutchins later tweeted: "Anyone got a kronos sample."

His mum, Janet Hutchins, told the Press Association it is "hugely unlikely" he was involved because he spent "enormous amounts of time" fighting attacks.

Research?

Meanwhile Ryan Kalember, a security researcher from Proofpoint, told the Guardian that the actions of researchers investigating malware may sometimes look criminal.

“This could very easily be the FBI mistaking legitimate research activity with being in control of Kronos infrastructure," said Kalember. "Lots of researchers like to log in to crimeware tools and interfaces and play around.”

The indictment alleges that Hutchins created and sold Kronos on internet forums including the AlphaBay dark web market, which was shut down last month.

"Sometimes you have to at least pretend to be selling something interesting to get people to trust you,” added Kalember. “It’s not an uncommon thing for researchers to do and I don’t know if the FBI could tell the difference.”

It's a sentiment echoed by US cyber-attorney Tor Ekeland, who told Radio 4's Today Programme: "I can think of a number of examples of legitimate software that would potentially be a felony under this theory of prosecution."

Hutchins could face 40 years in jail if found guilty, Ekelend said, but he added that no victims had been named.
